Genuine contact with nature is essential for the emotional and social development of young children. This notion is one of the ten principles of the French national charter for preschool childcare, created by ministerial decree on 23 September 2021. A number of facilities have already embarked on this path, supported by the association Label Vie, including the non-profit Mil'mouch nursery in Seine‑et‑Marne. The crops growing in the garden, along with the plants and the small animals in the green space, are all proving to be a solid foundation for learning. Best practices, particularly concerning sustainable food, are catching on among families, who get involved in the project through workshops.
